Operating Instructions
Basic Operation
- Power On/Off: Press and hold the power button (usually the volume/power knob) until the display illuminates or turns off.
- Volume Adjustment: Rotate the VOL/SQL PWR knob to adjust the audio volume.
- Squelch Adjustment: Press the VOL/SQL PWR knob briefly, then rotate it to adjust the squelch level. This eliminates background noise when no signal is received.
- Channel Selection: Use the CH Up/Down buttons to navigate through available channels.
- Channel 16 (Distress/Calling): Press the dedicated 16/C button for instant access to Channel 16, the international distress and calling channel. Press again to return to the previous working channel.
- Transmit: To transmit, press and hold the PTT (Push-To-Talk) button on the microphone. Speak clearly into the microphone. Release the PTT button to receive.
Advanced Functions
- AquaQuake Draining: This function vibrates the speaker to expel water, ensuring clear audio even after exposure to spray or rain. Refer to the on-screen prompts or manual for activation.
- Dual/Tri-Watch: Monitor Channel 16 and/or a call channel while operating on another channel. This ensures you don't miss important calls.
- Tag Scan and Favorite Channels: Program frequently used channels into a scan list or as favorites for quick and efficient monitoring.
- DSC (Digital Selective Calling): The built-in Class D DSC allows for automated distress calls and other safety-related communications. Ensure your MMSI (Maritime Mobile Service Identity) number is programmed into the radio.
Maintenance
Regular maintenance will prolong the life of your ICOM M330 VHF Marine Radio.
- Cleaning: Wipe the radio and microphone with a soft, damp cloth. Do not use abrasive cleaners or solvents.
